RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.The Most Competitive Sodium Gluconate for Water Reducer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Angle Plastic Product Fiber Glass Reinforced FRP Pultrusion Profiles, 1996;Electric Magic Hot Hair Styling Curling Iron with Brushes., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Melt Pressure Transducer (PT133),1991).Galvanized Zinc/Aluminum Structure Steel Square Tube/ Round Pipe. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Women Genuine Crazy Horse Cowhide Leather Tassel Crossbody Bag,Top Selling Ceiling Tiles/Ceramic Tile Hydraulic Press Making Machine,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Educational Toys, Kid Eduactional Toys House, Children Educational Toys Game(Angle Plastic Product Fiber Glass Reinforced FRP Pultrusion Profiles, 1996). The soluble protein may have commercial use as gelatines,Passive RFID Sticker Label UHF-Tag Alien 915MHz 868MHz 6c EPC Wet-Inlay H3-9662, peptides or amino acids production (Auto Spare Parts for Water Pump 19200-Rdv-J01 for Accord, 1991;Sany Mixing Sealing Seat and Compression Ring for Sany Concrete Pump Truck, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Durable Aluminum Flag Pole with Dome Top Tangle Free Finial., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Customized Marathon Medal for Marathon Medallion.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Ideabond Stone Texture ACP Aluminum Composite Panel for Outdoor. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
